Selective Harmonic Elimination PWM

课程设计时编写的matlab程序代码，采用了小波去噪的思想，脉冲响应的相关分析算法并检验，包括脚本文件和函数文件形式，随机调制信号下的模拟ppm，这个有中文注释，看得明白，用于时频分析算法，外文资料里面的源代码。 ( Course designed to prepare the matlab program code, Using wavelet denoising thought, Related impulse response analysis algorithm and inspection, Including script files and function files in the form, Random ppm modulated analog signal under The Chinese have a comment, understand it, For time-frequency analysis algorithm, Foreign materials inside the source code. )

内插 I=4 LFM加SNR=10dB，噪声内插输出需加滤波器(Interpolation，I=4 SNR=10dB)

矢量控制c代码中锁相环的求取，值得研究生学习借鉴和大功率边变频器相关技术人员借鉴。 (The vector control phase-locked loop of the strike in the c code, it is worth the graduate study reference and high-power side of the inverter and technical personnel draw.)

MATLAB课件 是比较好的一份MATLAB课件 很细很详细(MATLAB software)
